Yes, a steep drain, of a decent diameter (1.5"-2"?) would drain faster with less wetted surface.

I'd love to switch to something smoother and perhaps larger in diameter. Any reason not to go with, say, clear vinyl hose? Any suggestions for how to attach it to the porcelain?

To actually install them with a reasonable number of available hands you have to be able to guide the hose to fit into what in our case is a fixed vertical 2" ABS line. Perhaps the easiest is if the flex hose isn't flex at all or even positively attached to the porcelain unit but press fit so that when lifting the toilet (during installation or to troubleshoot issues such as we're discussing here) one doesn't have to be so careful about alignment in spaces that are very difficult to access--without bulimic children to send into tight crevices and many more hands than anyone I've met.
